What are the esophagus and its function?

The esophagus is a muscular channel that carries food from the pharynx to the stomach. It starts with the upper esophageal sphincter, formed in part by the cricopharyngeus muscle, and ends with the lower esophageal sphincter, surrounded by the crural diaphragm.
